EN35SXR128A-104FIP(2PC)

The EN35SXR128A-104FIP(2PC) from ESMT is a 128 Mbit serial NOR Flash memory organized as 16M × 8 for non-volatile code and data storage. It implements a SPI serial interface with support for Standard, Dual and Quad I/O modes and a 104 MHz fast-read clock to support high-throughput read operations.

Designed for industrial temperature operation, the device combines uniform-sector erase architecture, hardware and software write protection, and security features for applications that require reliable field updates, code storage, and secure non-volatile data retention.

Key Features

• Memory Capacity & Organization  128 M-bit device organized as 16M × 8 with 256‑byte programmable pages and 65,536 pages total.
• Serial SPI Interface  Supports Standard, Dual and Quad SPI I/O (CLK, CS#, DI/DO, DQ₂, DQ₃) with SPI Mode 0 and Mode 3 compatibility.
• High‑speed Read  Fast read operation up to a 104 MHz clock rate for Single/Dual/Quad I/O Fast Read.
• Uniform Sector Architecture  4,096 uniform 4‑Kbyte sectors (512 × 32‑Kbyte blocks; 256 × 64‑Kbyte blocks) enabling individual sector or block erase operations.
• Program & Erase Performance  Typical page program time 0.5 ms (500 µs); sector erase typical 40 ms; half‑block and block erase and chip erase times documented for system planning.
• Power  Single power supply operation across the device's specified voltage range with low active current (typical 8 mA) and ultra-low power down current (typical 0.1 μA).
• Security & Protection  Hardware and software write protection, lockable 3×512‑byte OTP security sector, Read Unique ID Number, and a Replay‑Protected Monotonic Counter (RPMC).
• Reliability  Endurance of a minimum 100K program/erase cycles per sector and data retention typically specified at 20 years.
• Package & Temperature  Surface mount 16‑pin SOP (300 mil) package with industrial operating temperature range −40 °C to 85 °C.

Typical Applications

• Firmware and Boot Storage  Stores boot code and firmware images where fast read performance and reliable non‑volatile retention are required.
• Field Updates & Code Patching  Supports selective block/sector protection and individual sector erase so systems can safely patch or update code modules in the field.
• Configuration & Parameter Storage  Secure storage for device configuration, calibration tables, and non‑volatile parameters with OTP and protection options.
• Embedded System Code Shadowing  Provides a serial Flash target for shadowing application code or storing secondary images for safe firmware rollbacks.

Unique Advantages

• Flexible I/O Modes: Standard, Dual and Quad SPI support enables designers to scale read bandwidth to match system requirements.
• Fine‑Grained Erase Control: Uniform 4 KB sectors allow selective erasure and updates without requiring large block or full chip erase cycles.
• Fast Read Throughput: 104 MHz fast‑read support delivers higher read performance for boot and execute‑in‑place use cases.
• Industrial Temperature Range: Specified operation from −40 °C to 85 °C for robust performance in industrial environments.
• Low Power Standby: Very low power down current (≈0.1 μA typical) supports energy‑sensitive designs that require long idle periods.
• Security & Longevity: OTP, unique ID, RPMC and a minimum 100K P/E cycles plus 20‑year data retention help ensure long‑term reliability and secure operation.
